With no buttons or switches for normal operation, the Micro III delivers permanent safety, allowing you to devote your full attention to essential work. Designed for safety Weighing less than 4 ounces, the Micro III comes equipped with 95 dB horn, ultra bright LEDs, and three alarm points that will alert the user to increasing hazards. A high impact ABS casing seals the unit from water, and a layer of titanium resists damage and RF interference. GfG's Micro III features include: minimal maintenance, user-replaceable, two-year warranted sensors, and powered from a user-replaceable “AA” alkaline battery that provides up to nine months of run time. The durability, ease of use and low maintenance make the Micro III an investment that will last for many years. The long-life sensors of the MICRO III are user replaceable through pre-calibrated spare sensors. The detector itself does all further adjustments. The MICRO III offers 3 threshold alarms and a battery alarm, thereby ensuring a full personal protection. The loudness of the audible alarm with its changing frequency gets improved by means of a resonance cell. In addition to this, in case of an alarm, the two 360º visible, ultra-bright LEDs are alternately flashing.
